Definitions

• the present invention relates to a process for production of containers for cosmetic products.
• the present invention relates to a process for the production of containers and a respective container specifically used in the cosmetic field for the retention of liquid, semi-liquid or pasty products, such as mascara, lip gloss, lipsticks, enamels, etc.
• containers for cosmetic products consist of a substantially cylindrical body, generally made of plastic and defining internally a containment chamber of the cosmetic product.
• the body has a closed bottom end and an open upper end for accessing the containment chamber of the product. From the open end a threaded collar emerges for the coupling of a respective closure cap.
• the cap is associated with an applicator brush, immersed in the product in the closure condition of the container, and is capable of retaining the cosmetic product and distributing it to the affected part (eyelashes, in the case of mascara).
• the body also has an outer surface properly shaped and provided with writing, logos or other chromatic / ornamental effects suitable to give the whole product a particular aesthetic effect.
• cover elements to be coupled to the outer surface of the cylindrical body.
• the cover element is specially designed to give a greater ornamental value to the entire product. Accordingly, cover elements also having a predominantly cylindrical conformation and being internally hollow to hold the body are manufactured.
• These elements are made of metallic material (or similar materials) which can have multiple solutions in terms of external colouring or shaping.
• the cover elements are obtained by a moulding or drawing process starting from a sheet of metal material.
• the moulds are properly arranged to plastically deform the metal sheet, thus obtaining the internally hollow cylindrical conformation.
• this process allows to obtain ornamental patterns on the outer surface of the cover element.
• the printing of the cover element is a non- versatile process, as it involves the production of suitably shaped moulds.
• the object of the present invention is therefore to provide a process for the production of containers for cosmetic products which is capable of solving the above-mentioned problems.
• an object of the present invention is to provide a process for the production of containers for cosmetic products that is versatile and capable of being adaptable, in a simple and cheap way, to the various aesthetic characteristics that the container must exhibit.
• Another object of the present invention is to provide a process for manufacturing a container for cosmetic products having high qualitative characteristics as well as a valuable ornamental effect.
• the mentioned technical task and the specified aims are substantially achieved by a process for manufacturing a container for cosmetic products, including the technical specifications set out in one or more of the appended claims.
• FIG. 1 shows a side elevational view of a container for cosmetic products manufactured with the process according to the present invention
• Figure 2 is a longitudinal sectional view of the container of Figure 1 ;
• FIG. 3 is a longitudinal sectional view of a part of the container of Figure 1 according to a second embodiment shown as an example.
• FIG. 4 is a longitudinal sectional view of a part of the container of Figure 1 according to a third embodiment shown as an example.
• reference numeral 1 refers, as a way of example, to a container for cosmetic products obtained by the process of the present invention.
• the process comprises the step of providing a first bar made of metal or metal alloy and then turning the first bar to obtain an element 2 having a tubular shape and defining internally a housing compartment 3.
• a first bar is prepared, preferably in aluminium alloy or another material having the same structural characteristics.
• the manufacturing process involves a turning step of an inner area of the first bar to define said compartment 3 having a cylindrical shape and defining an access opening 4 of the compartment and a closed end 5 opposite to the access opening
• the turning operation further involves the step of turning an outer surface 6 of the first bar to define an external silhouette of the tubular element 2.
• the outer surface 6 may have any shape according to the desired aesthetic aspect of the container 1 .
• the first bar is turned to define an outer surface 6 having a variable section along the longitudinal development.
• This variable section defines in particular a central collar 7 protruding with respect to the rest of the surface.
• the first bar may be turned to provide on the outer surface 6 a configuration determined by end portions 8 bent towards the inside. This configuration is better illustrated in the cut through of Figure 3, wherein an element 2 is represented according to a different embodiment solution.
• the first bar can be turned to define a cylindrical outer surface 6 (Fig. 4) with a circular section, and therefore having a constant section throughout the longitudinal development.
• the turning step is implemented in order to define any external configuration of the element 2, realizing surfaces 6 that can exhibit different aesthetic effects.
• the element 2 thus obtained undergoes an anodizing step to achieve a finishing process of the surface.
• This anodizing step is carried out to give a specific external ornamental appearance, such as a specific stain of the outer surface 6 of the element 2. Finally, it is inserted a cylindrical body 9 for containing the cosmetic product inside said housing compartment 3 ( Figure 2).
• the cylindrical body 9 is preferably made of a plastic material suitable for containing cosmetic products without altering their chemical characteristics.
• cylindrical body has dimensions suitable to be contained in the compartment 3 and engaged inside the compartment 3 by mechanical interference.
• the step of inserting the cylindrical body 9 into the compartment 3 is accomplished by inserting the body 9 through the access opening 4 so as to project at least a threaded neck 9a of the cylindrical body 9 out of the housing compartment 3.
• a closure cap 10a is advantageously provided to be engaged with the threaded neck 9a of said cylindrical body 9.
• the closure cap 10a is produced by providing a second bar made of metal or metal alloy, preferably in aluminium alloy.
• the second bar is turned to obtain a cap 10 defining internally a housing compartment 1 1 .
• the turning step provides a sub-step of turning an inner zone of the second bar to define the compartment 1 1 countershaped to the cap 10a and turning an outer surface 12 of the second bar to define an outer shape of the cap 10.
• the turning steps allow to obtain any shape and dimension of the outer surface 12 from a full bar.
• Figure 1 and 2 show a cap 10 having a cylindrical shape with a circular section.
• the cap 10 is also anodized to obtain a finishing process of the surface, such as the colouring of the external surface 12.
• the cap 10a is inserted inside the compartment 1 1 of the cap.
• the cap 10a may be provided with an applicator 13 of the cosmetic product, such as a brush that is inserted into the body 9 in the closure condition of the cap.
• the process does not require the preparation of moulds, but only the programming of appropriate turning steps to produce products having any shape.
• the turning step of bars is simple and very cheap because it does not involve the study, preparation, design and manufacture of moulds, and does not necessarily need to be carried out with metal sheets of a predetermined thickness. Consequently, this step is very versatile as it allows to easily adapt and modify, therefore in a cheap way, the outer shape of the container 1 even for low quantities.
• the turning step enables the production of tubular elements 2 housing the plastic bodies 9 for containing the cosmetic product with different thicknesses.
• the bar is internally turned in order to produce the compartment 3 and thereby determining a thickness of the tubular element 2 capable of adapting to the different needs. Such thickness can also be high to give a better aesthetic and qualitative value to the completed container 1.
• the metallic material (aluminium alloy or other) is very durable and, at the same time, has very versatile characteristics in terms of adaptability to the different surface finishes.
